On an ISR G2 running CME, when "debug voice application error" is enabled, the logs are continually flooded with the error:
//-1//TCLM:/tcl_hunt_group_num_calls_in_callq: B-ACD-SERVICE Tcl service not available
I have tried installing the b-acd scripts which had no effect. Even with no TCL applications configured, the above error is logged every few seconds with this debug.
I saw the following bug and tried downgrading to version 15.7(3)M4a, as well as version 15.7(3)M5 (which is specifically supposed to have the fix), even though the latest 15.7(3)M8 (which it was originally running) is not supposed to be affected anyway. No difference.

Any ideas? I find it hard to believe this is normal.
